Communicating Thermostat
SuperSTAT SZ1051
Introduction
Congratulations on choosing the SuperSTAT™ Thermostat SZ1051! The SuperSTAT
series of thermostats are feature rich, multifunction devices providing
extensive controls across a wide range of HVAC applications.
Complete the configuration after installation (refer to the SZ1051/1053
SuperSTAT Installation Manual for instructions on mounting the device, wiring
the communications network and connecting other devices to the SuperSTAT.)
Your configuration settings will be uploaded to Ubiquity Cloud the first time
you make a connection to the site. Alternatively, you can skip configuring the
SuperSTAT via the keypad and perform all configurations via Ubiquity Cloud, or
via a PC running TCS Insight software, which is available for download on the
TCS website.
NOTE: When configuring the SuperSTAT via a connected PC, you must first
set the SuperSTAT’s address, baud rate, and temperature scale using the keypad
(see “Programming Keypad Access” on page 4).
If you have any questions regarding your SuperSTAT, do not hesitate to contact
TCS Technical Support at 800.288.9383, ext. 2. Our Technical Support
Department hours are Monday – Friday, 7:00 a.m. to 7:00 p.m. (CST).
Display Screen and Keypad
The display screen on the right side of the cover provides at-a-glance
information including day, date, time, and temperature (based on sensor
selection and wiring).
Locating the Programming Keypad
The SuperSTAT is programmed through a keypad behind the panel on the left side
of the cover. Access the keypad by swinging open the cover panel.
Programming Keypad Access
The keypad can be configured to restrict access to the Programming Setup and
Clock and Schedule functions. You can control the access to either function by
configuring the keypad dip switches on the inside of the front cover as
shown.
Navigating Via Keypad
All settings on the SuperSTAT can be made via the keypad. Each screen will
display the name of the setting, a selection option, and current values for
that screen, which will flash to indicate which is active. Pressing the WARMER
button will increase the value or advance the active setting to the next
option on the screen; pressing the COOLER button will reverse the process. For
screens with multiple values (e.g., date setup), pressing the OVERRIDE button
will advance you to the next value. After adjusting the values, press the
PROGRAM SETUP or CLOCK SETUP button again to save the values and advance to
the next screen.
NOTE: Press and hold the PROGRAM SETUP, CLOCK SETUP, WARMER, or COOLER
buttons in order to scroll through screens and values more quickly. Press the
SERVICE STATUS button to exit PROGRAM SETUP Mode or CLOCK SETUP Mode and
return to the main screen.
Keypad Button Functions
| Press to change fan speed and system modes (when enabled)| | Press to raise
or lower temperature settings when OCCUPIED LED is on
| Press to change fan thermostat’s program or temperature setback times (when
enabled)| | Press when
OCCUPIED LED is off to restore occupied
temperature settings
| Press to review service screens
Program Setup Mode
Before entering PROGRAM SETUP Mode, ensure that the temperature sensor dip
switch settings match your intended use (see the SZ1051/1053 SuperSTAT
Installation Manual). If the dip switch settings do
not match the configuration settings in this section, the SuperSTAT will not
function properly.
NOTE: PROGRAM SETUP Mode can be disabled via dip switch settings (see
“Programming Keypad Access” on page 4, or access can be restricted by
requiring an access code (see “Keypad Access Code” on page 10).
The main screen displays when not in PROGRAM SETUP Mode or CLOCK SETUP Mode.
The SuperSTAT will revert to this screen if no entries are made after 10
minutes.
From the main screen, press the PROGRAM SETUP button on the keypad to
configure the settings.
If the SuperSTAT has been configured to require an access code to enter
PROGRAM SETUP Mode, this screen will appear (see “Keypad Access Code” on page
10). If you enter the wrong code, the screen will revert to the main screen.
